All figures are foot-pounds. Where a source publishes in inch-pounds, the conversion is noted alongside it rather than the raw number being carried over.

Figures cross-checked across JEGS, Summit Racing, TorkSpec and older published tables. Where sources disagree, both are shown rather than averaged. Always defer to the sheet packed with an aftermarket part, and to a GM service manual for your specific year.

Reference only: use at your own risk and verify every figure against your service manual. Not affiliated with or endorsed by any vehicle, engine or parts manufacturer; all brand and model names are trademarks of their owners. Full disclaimer
